MEaSUREs Greenland Ice Mapping Project (GIMP) Digital Elevation Model from GeoEye and WorldView Imagery, Version 1

This data set consists of an enhanced resolution digital elevation model (DEM) for the Greenland Ice Sheet. The DEM is derived from sub-meter resolution, panchromatic stereoscopic imagery collected by the GeoEye-1, WorldView 1, WorldView 2, and WorldView 3 satellites operated by DigitalGlobe Inc. The imagery is distributed by the National Geospatial Intelligence Agency (NGA) and archived at the Polar Geospatial Center at the University of Minnesota through the NextView License program. Although the source images are subject to user restrictions, derived products including DEMs may be openly distributed for non-commercial purposes. See Greenland Ice Mapping Project (GIMP) for related data本数据集包含格陵兰冰盖的增强分辨率数字高程模型（digital elevation model, DEM）。该DEM源自数字地球公司（DigitalGlobe Inc.）运营的GeoEye-1、WorldView 1、WorldView 2及WorldView 3卫星采集的亚米级分辨率全色立体影像。 该影像由美国国家地理空间情报局（National Geospatial Intelligence Agency, NGA）分发，并通过NextView授权计划归档于明尼苏达大学极地地理空间中心。尽管源影像受用户使用限制，但包括DEM在内的衍生产品可面向非商业用途公开分发。 相关数据可参考格陵兰冰盖制图项目（Greenland Ice Mapping Project, GIMP）
